Analytical methods utilizing correlated electroanalytical and optical measurements are presented which enable detailed studies of the electrochemical properties of individual nanostructures. Scanning electrochemical microscopy is employed to directly measure the rate of electrochemical reactions at individual nanoparticles, while optical spectroscopy is used to probe the structure of these particles in situ. This enables the correlation of electrochemical kinetic data with particular particle structures, providing valuable insights into structure-function relationships for a given electrochemical process. Additionally, in situ spectroscopic measurements facilitate investigations into the mechanisms responsible for transient changes in electrochemical reactivity (e.g., catalyst deactivation). Initial studies applying the described methods to model electrocatalytic systems are presented.
